Abstract

The genus is composed of prosthecate bacteria often specialized for oligotrophic environments. The taxonomy of has relied primarily upon morphological criteria: A strain that visually appeared to be a member of the has generally been called one without challenge. A polyphasic approach, comprising 16S rDNA sequencing, profiling restriction fragments of 16S-23S rDNA interspacer regions, lipid analysis, immunological profiling and salt tolerance characterizations, was used to clarify the taxonomy of 76 strains of the genera and . The described species of the genus formed a paraphyletic group with , Caulobacter fusiformis, and comb, nov.) belonging to comb, nov.), subsp. aurantiacus ( comb, nov.), comb. nov.), subvibrioides ( comb. nov.), subsp. albus ( comb. nov.), comb. nov.) and belong to the genus . The halophilic species and are different from these two genera and form the genus gen. nov. with as the type specis was observed to cluster with species of the genus with and with as determined by these analyses and DNA-DNA hybridization. Biomarkers discerning these different genera were determined. The necessary recombinations have been proposed and a description of is presented.
